03 gt performance chip

howdy
haven't visited this forum since 2004, but now have a question that you can help answer. I have an 03 GT and would like to know if a performance chip is worthwhile installing. I would considering purchasing one that would not activate
CHECK ENGINE light. What make, model and where is it available [on-line ?]

Nice to be back and any information is apreciated.
Thanks
Charlie

mods please....

handheld, or dyno tuned?

dont you have you to run super unlead in the car after the mod chip? with the price of SU gas now-a-days , does the little bit of gain you will see with a chip justify the means?

 

[centencharlie]

i am looking at hand held.

Do all the performance chips require 91 octane?
This is the kind of info or advise I am requesting.
what chip have you installed and have had a positive go with it.

thank you for the replies

get yourself a timing adjuster and call it a day.

Custom dyno tune to a chip...or nothing at all
